TEST PRINCIPLES AND NOTES ON INDIVIDUAL PARAMETERS
CONBUR TES
Test strip for the semiquantitative determination of specific gravity, pH, leukocytes, nitrite, protein, glucose, ketone bodies, urobilino- gen, bilirubin, and blood in urine by visual reading
- When withdrawing the test strip, wipe the edge against the rim of the vessel t remove excess urine 5. After 60 seconds (60-120 seconds for the leukocyte test compar the reaction colors of the test areas with the colors on the label and assign always th color block.
- the 9th or 10th (blood test area with both color scales as separate color scales are given for erythrocytes and hemoglobin.
- Any color changes appearing only along the edges of the test ar or developing after more than 2 minutes, do not have any diagnostic significance.
- pH: The pH values found most frequently in fresh urine from healthy individuals lie between 5 and 6. The test is specific for the detection of hydronium ions, the pH being the negative common logarithm of the hydronium ion concentration. The test pad contains the indicators methyl red, phenolphthalein and bromothymol blue
- Leukocytes: The reaction detects the presence of esterases that occur in granulocytes These enzymes cleave an indoxyl ester, and the indoxyl so liberated reacts with a diazo-
- Nitrite: The most common organisms causing urinary tract infections, Eco urinary pathogens, convert di-etary nitrate to nitrite, which produces a pink to red coloration of the test area. The reaction thus indirectly detects the presence of nitrite- forming organisms in the urine Even a slight pink coloration is an indication of significant bacteriuria,
